3 Claims. (Cl. 215-43) The invention relates to a jar and closure ofspecial design.

More specially the invention relates to a closure cap for a jar having asubstantially spherical surface surrounding the opening therein.

Fig. 1 is a face view of my new cap-and-jar unit, in fitted position.The jar rim is inverted into a vise-type section of the cap between aninner screw closure and outer cover which curves to the jar roundness,numeral 1 showing the same spherical curvature.

Fig. 2 is the top view of the cap and jar, numerals 2 and ZA showing thespherical shape of the unit.

Fig. 3, numeral 1A is the same curvature as shown in Figure l,numeral 1. Numeral is the part of the jar cover which extends over theouter lip of the jar, completing the double grip closure of the cap,which holds the jar lip in vise-type spill-proof security. Numerals 6and 6A show the metal prongs on the inner curvature of the cap as a partthereof, and around these prongs, numeral 7, shows a plastic fillerwhich afiixes the outer cap and its threaded core. Numerals 8, 3A and 4Ashow the thread positive in closed position. These threads are formed asshown so that when turning the cap to the right hand it screws into thelip of the jar which is the thread negative as indicated in numerals 3,4 and 5A. When the cap is screwed into its closed position onto the jar,the lip is held in double vise grip spill-proof position as the cap andjar unit. Numeral 9 indicates the roundness of the jar.

Fig. 4 shows the jar cap in full line of the under cover view. Numeral11 is the thread core. Numeral shows the positive screw threads thereon.Numeral 10A shows the outer cover curvature which extends over the jarwhen the two units are fitted together in compleion as the unit.

I claim the invention of:

1. A receptacle for cosmetics, pharmaceuticals and the 2,981,431Patented Apr. 25, 1961 like comprising a hollow body member the upperportion of which is of substantially spherical external surfaceconfiguration and is provided with an opening therethrough the walls ofwhich opening are formed with an internal screw thread, and a closuremember comprising a plug portion having an external screw threadreceivable within said opening complementary to said internal screwthread and a skirt portion symmetrically arranged with respect to thethread axis of said plug portion, the undersurface of said skirt portionbeing of spherical configuration conformant to the external sphericalsurface of said body member and adapted to overlie, bind and seal uponsaid external spherical surface when assembled therewith.

2. A receptacle for cosmetics, pharmaceuticals and the like comprising ahollow body member the upper portion of which is of substantiallyspherical external surface configuration and is provided with an openingtherethrough the walls of which opening are formed with an internalscrew thread, and a closure member comprising a plug portion having anexternal screw thread receivable Within said opening complementary tosaid internal screw thread and a thin skirt portion symmetricallyarranged with respect to the thread axis of said plug portion, saidskirt portion being of spherical curvature conformant to the externalspherical surface of said body member and adapted to seal thereupon whenoverlying same under the threaded assembly of said plug portion withsaid body member.

3. A receptacle for cosmetics, pharmaceuticals and the like comprising ahollow body member the upper portion of which is of substantiallyspherical external surface configuration and is provided with an openingtherethrough the walls of which opening are formed with an internalscrew thread, and a closure member comprising a plug portion having anexternal screw thread receivable within said opening complementary tosaid internal screw thread and a skirt portion concentrically encirclingsaid threaded plug portion, the internal surface of which skirt portionis of spherical configuration complementary to said spherical surface ofthe body member and so arranged as to seat thereon, constrictively, whensaid plug portion is forceably threaded into said body member.
